Midcycle Bleeding TTC

I have been off birth control since May because my husband and I are ready for baby 2. I have been having a lot of midcycle bleeding and unsure pf ovulation since. This month I decided to opk. Well on day 13 it said ovulation, then day 14 no, then day 15 yes. I am on day 15 now and have been bleeding since yesterday. Its getting heavier too. I just want insight from anyone else experience/d this, I am beginning to get worrisome and anxious, which doesn't help with TTC...
